@Charlie2019 Hi. The only support group I've been able to find in Brisbane is connected to the Wesley Hospital. You don't have to be having any treatment with them to join the groups. It's open to anyone. It's called the Wesley Hospital Choices Cancer Support Centre. They have a structured program running Mon - Fri during work hours.

Other than that, I haven't been able to find anything else in Brisbane. I get fobbed off with people saying phone the Cancer Council. I find it very annoying. It's something that I think BC nurses for example should know. Or at least have a list of direct phone numbers e.g. here's the southside support group number. Not just a generic 13 number.
I know the Wesley isn't that close to Yeronga but at least you can get connecting trains if you don't want to drive and pay exorbitant parking fees!
